Description
Technical field
The present invention relates to the communications field, be specifically related to a kind of information dispensing method and system.
Background technology
Cloud computing (CloudComputing, CC) is a kind of effective means improving network resource utilization, reduction energy resource consumption in Internet field, has obtained common concern and the partial deployment of industry at present. In cloud computing, Internet can be abstracted into cloud (i.e. data center, DataCenter (DC)), pipe (pipeline), end (terminal) three part. By the resource (calculating resource, storage resource and Internet resources) in data center is carried out virtualization collecting, after carry out cutting into slices (Slicing) process, the resource after processing is distributed according to need to tenant (Tenant). When the server (Server) carrying customer service breaks down, can will run the virtual machine (VirtualMachine of the business of tenant in real time, VM) and storage and Internet resources from failed server migrate (Migrate) go to new server, which enhance the reliability of service operation. In cloud computing, in order to be able to provide dynamic network service to more tenant, some large-scale data centers have the ability of the virtual network (realizing isolation and the interior intercommunication of net between the net of tenant's flow) supporting 16,000,000 (24 powers of 2) multiple. Virtual network is a kind of stacking network (OverlayNetwork) technology, namely, on same physical network infrastructure device (PhysicalNetworkInfrastructure), different logic network (LogicalNetwork) is fictionalized by superposing means.
After migrating in order to avoid VM, its MAC (medium access control)/IP address etc. changes, bringing impact (such as interrupting and reconstruction etc.) to session (Session) original between VM, VM migrates to be needed to implement in two layers of (Layer2) network. The heart in the data, especially supports in virtualized data center, and the migration of VM needs to carry out in big double layer network. TRILL (TRansparentInterconnectionofLotsofLinks, multilink transparent interconnection) it is that international mark organizes IETF (InternetEngineeringTaskForce, Internet engineering duty group) the big two layers of technology of one defined. Simultaneously, in order to improve in TRILL network, the real-time (Timely) of the MAC Address distribution of end system (EndStation) and safety (Security), TRILL working group is that MAC Address notice defines ESADI (EndStationAddressDistributionInformation, end system address distribution information) agreement.
ESADI provides quick, the safe distribution means of the MAC Address of (VirtualNetworkScoped) end system (VM or server) within the scope of a kind of virtual network. Enabling the network equipment of ESADI agreement, be commonly referred to ESADI route-bridge (that is, ESADIRBridge), it can individually enable an ESADI example in each virtual network, is responsible for distribution and the synchronization of the MAC Address of VM in this virtual network. In same virtual network, neighborhood can be formed between ESADI equipment, and elect a RBridge as specifying route-bridge (DesignatedRBridge, DRB). By periodically sending CSNP (CompleteSequenceNumberPacket, sufficient sequence message), DRB mono-aspect notifies other ESADI equipment, and it is still located in working order, the synchronizing information being used on the other hand driving in same virtual network between ESADI equipment, such as: the positional information of VM and up to information. The notice cycle of current CSNP is 30 seconds.
In the data center that scale is less, this information distribution of ESADI and synchronization mechanism can actually play quick, safe information distribution effect, bring impact without to network traffics. but in large-scale data center, when especially wherein there is the virtual network of flood tide, in units of virtual network, set up neighborhood and distribute CSNP synchronizing information, bring huge Message processing to bear can to ESADI equipment, also can bring very big impact to network traffics simultaneously. such as: in the data center enabling 1,000,000 virtual networks, in 3 milliseconds, DRB is accomplished by producing 100 CSNP messages, and the CPU of other ESADI equipment is also required to complete this 100 Message processing in 3 milliseconds. in addition, along with ESADI accesses the infiltration of the application such as (Active-ActiveAccess) and directory assistance service device (DirectoryAssistServer) to the dual-active of TRILL, same server is (such as: as the gateway of the data center Underlying portal, or the LIST SERVER (DirectoryAssistantServer) as MAC information distribution center) almost can enable ESADI agreement in each virtual network, so that they ESADI Message processing burdens huge in facing, cause DOS (DenialofService further, refusal service). DOS can affect client and access the normal issue of data center or data center's internal mac information from outside.
